Specification of Letters Patent. l

. Patented Nov. 7. 1905,

Application filed March 2,1905. Serial No. 248,167.

T0 all whom, t may concern:

Be it known that I, GEORGE S. BUCK, a citi- Zen of the United States of America, residing at Kalispell, in the county of Flathead and State of Montana, have invented certain new and useful Improvements in Gates, of which the following is a speciiication.

This invention relates to gates, and more particularly to that class known as sliding gates.

It is an object of the invention to produce a gate of this character that will be operated automatically from a trackway provided for a vehicle.

It is also an object of the invention to provide a gate of the class in which a tilting trackway is provided for opening or shutting the gate, said gate having pivoted thereto a wheel or segment adapted to engage said track.

Another object of the invention is to provide means in a gate of this kind whereby the weight on the operating-wheel 0f the gate may be adjusted.

Still further, it is the object of the invention to produce means whereby the gate cannot be operated unless a vehicle approaches the gate, or, in other words, means is produced to prevent the accidental opening of the gate.

The invention has also for an object the provision of means for guiding the gate in its operation or holding it against lateral displacement.

A further object of the invention is to provide means, suoli as weights, on the operating wheel or segment to facilitate the movement thereof.

Further, it is an object of the invention to produce a device of this character that will be simple in construction, eiiicient in practice, and economical to manufacture.

With the above and other objects in view the invention consists in the details of construction and in the arrangement and combination of parts to be hereinafter more fully described and claimed.

In describing the invention in detail reference will be had to the accompanying drawings, forming part of this specification, wlierein like reference characters denote corresponding parts in the several views, and in which- Figure l is a view in side elevation and partly in section of the invention, the gates being closed. Fig. 2is aview similar to Fig.

1 with the exception that the gates are open.

Fig. 3 isa top plan view of the invention. Figs. 4, 5, 6, and 7 are views in detail of the locking mechanism of the gates. Figs. 8, 9, and l0 are views illustrating a modified means for operating the gate.

In the drawings, 1 indicates fence-posts of ordinary construction, and 2 guide-strips suitably secured thereto. It is to be noted that only the frame of the fence and gates are illustrated, the details of the fence and gate construction being omitted, as they form no part of the invention.

This invention pertains more particularly to double-gate construction, and in order to make the description of the invention clearer reference will be had to one of the gates only, it being understood that the gates are similar, with the exception of the locking means, which will be described in detail.

Pivotally secured. at one end to one of the posts l is a track 2, said track terminating at its opposite end at a point approximately flush with the gate-opening. This track consists of two parallel strips suitably spaced apart and provided with the series`of crossstrips 3, which forms a ladder-like construc- This arrangement is to produce a gripping means for the operating means of the gate to be later described. Although this is the preferred form, a rack of any construction may be substituted. Near the free end of the track there is provided in one of the parallel strips an elongated slot 4. Movably secured within this slot 4 is an end of a bellcrank 5, the opposite end of the crank being pivotally attached to an end portion of a strip 6, resting within a ytrackway 7. This trackway is of a boxlike structure and is provided at one end with an opening 8, through which the bell-crank or lever 5 passes. This trackway extends a suitable distance from the gate, and at its outer end or near said end is pivoted the strip 6, as at 9. The arrangement of parts is such that when the gates are closed the strip is slightly above the trackway. This strip is adapted to be engaged by the wheels or support of a vehicle, through which medium the gate is operated.

The gate consists of the end strip l0, rear strip ll, bottom strip 12, and the top strip 13. Mounted on the rear strip l1 is a support 14 for the gate. This support may be a wheel, as indicated in dotted lines; but I prefer to employ a segment of a wheel. The periphery IOO of the segment is provided with a series of teeth 15, adapted to engage the cross-pieces 3 of the trackway 2. Normally this trackway is in a horizontal position, or possibly slightly inclined downward, in which position the gate is closed. Vhen the strip 6 is depressed, the' trackway by means of the bellcrank is elevated and the segment rolls or travels backward, and thereby opens the gate. To facilitate this movement, a weight 16 is provided on the segment in such a way as to cause the gate to open quickly and after the trackway has regained its normal position to close slowly. By this arrangement suflicient opportunity7 is given for the passage of a vehicle through the gate-opening. Upon a vehicle leaving the strip 6 the gate will ordinarily return to its closed position by its own weight or gravity; but to make the return positive the strip 6 extends a slight distance beyond its pivotal point 9. Through this means the weight of the vehicle will give an opposite movement to the bell-crank 5 just before it leaves the strip.

The top strip 13 of the gate extends beyond one side thereof and is provided with a series of depending straps 17, adapted to ernbrace the guide-strip 2. These straps hold the gate in operative position and also prevent any lateral movement thereof. On the free portion of the top strip 13 is mounted a slidable weight 18, through which medium the weight of the gate can be adjusted on the fulcrum-point 19 of the operating segment or wheel 111. This adjusting' of the gate greatly assists the operation of the gate.

The track-approach 7 is provided on each side of the gate, together with similar connections between it and the trackway 2, in order that the gate may be operated by a vehicle coming in either direction.

It is the intention of this invention that the gates shall only be operated or opened when pressure is on both of the tracks of the approach; otherwise the weight of live stock and the like may be given to one of the tracks. which in itself would be sufficient to elevate the trackway 2 and open the gates. To prevent this, an opening 20 is formed in the end piece 10 of one of the gates and an arrowshaped lever 20 is pivoted in the end or abutting piece of the opposite gate. This arrow is adapted to pass through the opening 2O when the gates are in a closed position, as illustrated in Fig. 7. If suflicient weight is placed on the left-hand strip 6 to raise the track 2, the lower edge of the opening 2O will engage the lower part of the arrow 21 and the gate will be locked against movement. If suflicient pressure is made on the opposite side, the arrow 2l will engage the upper edge of the opening 20; but if suflicient pressure is exercised on both simultaneously the gates will be raised and the arrow 21 will be free to pass through the opening 20, allowing the gates to open. These features are illustrated in detail in Figs. 4, 5, 6, and 7.

In Figs. 8, 9, and 10 is illustrated a modified means for operating the gate or elevating the tracks. In these figures the gate or gates a and. the trackway b, together with their parts, are constructed the same as in the preceding iigures. Extending across the gateway and in aliner'nent therewith is a housing c, the upper surface of which is flush with the surface of the roadway. Within the housing is a cross-bar (Z, having on each end an upright bar e, which passes through suitable openings or apertures f in the upper surface of the housing c. The upper ends of the bars e are suitably secured to the ends of the trackways and are adapted to elevate the same. A wagon-way f/ or boxing is made to approach the gate from either side, and within this boxing are pivoted near one end the levers t, which have one end suitably attached to the cross lever or bar d. A pivoted top or cover ,7' is provided for the boxings and is so arranged that the weight thereon of a vehicle will force the same against the free end of the lever t, and by means of the lever Z and the uprights e the trackways Z) are elevated to operate the gate. This form of invention is much simpler than that described before; but in practice it is found to be eflicient, economical, and advantageous.

From the foregoing descriptions it is thought that the construction and operation of the invention will be fully understood, it being' noted that all changes may be resorted to that fairly fall within the scope of the claims attached hereto.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is
